Article Synopsis
  • - Norovirus accounts for 18% of acute gastroenteritis (AGE) cases globally, and this study focuses on its incidence in Lima, Peru, while exploring the potential effects of introducing a norovirus vaccine.
  • - In a 6-month study involving 498 healthy children aged 5 to 18 months, researchers found that 32% of AGE cases were positive for norovirus, with a significant number of co-infections from bacteria like Campylobacter and Salmonella.
  • - The findings indicate that norovirus is a major cause of AGE in this population, highlighting the need for an effective vaccine to improve public health outcomes, especially given the high coverage of the oral rotavirus vaccine among the children studied.

Background: Although Peru provides safe and effective influenza vaccines free-of-charge, coverage among vaccine target groups like pregnant women and older adults remains low. To improve risk communication messages and vaccine uptake, we explored knowledge, perceptions and practices about influenza illness and vaccination.

Methods: A cross-sectional, community-based survey with a three-stage cluster sampling design was conducted in three cities in Peru.

Genital warts (GW) are mucosal or skin lesions caused by sexual transmission of human papillomavirus (HPV). This study estimates the frequency of GW cases in physicians' clinics and physicians' usual practices of GW referral and diagnosis in Peru. Participants in this study were a convenience sample of 100 physicians in five specialties: primary care (17), gynecology (37), urology (10), dermatology (31), and infectious diseases (5).

Background: The World Health Organization identifies pregnant women as at high-risk for severe influenza, but influenza vaccines are underutilized among pregnant women. Data on influenza burden during pregnancy are largely limited to high-income countries and data on the impact of influenza on birth and perinatal outcomes are scarce.

Methods/design: This prospective, longitudinal cohort study of pregnant women in middle-income countries is designed to address three primary objectives: 1) to evaluate the effect of laboratory-confirmed influenza during pregnancy on pregnancy and perinatal outcomes; 2) to estimate the incidences of all-cause acute respiratory illness and laboratory-confirmed influenza during pregnancy; and 3) to examine the clinical spectrum of illness associated with influenza viruses.

Objectives: HIV and other sexually transmitted infections remain a challenge globally and many key groups have yet to be studied. Evidence shows that truck drivers may have high-risk behaviors and higher sexually transmitted infection/HIV prevalence because they are a highly mobile population. However, there is little to no information on this group in Peru.

Background: Prevention and control of chronic diseases is a high priority for many low- and middle-income countries. This study evaluated the feasibility and acceptability of training pharmacy workers to provide point-of-care testing for 3 chronic diseases-hypertension, diabetes, and anemia-to improve disease detection and awareness through private pharmacies.

Methods: We developed a multiphase training curriculum for pharmacists and pharmacy technicians to build capacity for identification of risk factors, patient education, point-of-care testing, and referral for abnormal results.

Objectives: Chlamydia trachomatis, which is asymptomatic in most women, causes significant adverse effects for pregnant women and neonates. No programmes conduct antenatal screening in Latin America. We determined chlamydia prevalence, feasibility and acceptability of chlamydia screening, and adherence to treatment in pregnant women in two urban public hospitals in Lima, Peru.

Objectives: Untreated maternal syphilis leads to adverse pregnancy outcomes. The use of point of care tests (POCT) offers an opportunity to improve screening coverage for syphilis and other aspects of health systems. Our objective is to present the experience of the introduction of POCT for syphilis in Peru and describe how new technology can catalyze health system strengthening.
